GREAT BRITAIN sro-UT Fon. ein DRUMS, cANs, FIRE nXTiNGUisHEus, AND THE Linn f lAppncation ined Marea ie, i931, seriai naaaeis, ami in Great Britain December' 2, i930.

, This invention relates toimproveinents in `spouts' for drums, cans, fire extinguishers or other containers for oil or liquid and refers more particularly to pouring spouts for heavy oil such as for instance engine oils and heavy fuel oil. 1 v i With oils of this type or other liquids where the ow is sluggish and the rate offiow relatively slow owing to the viscosity'of the oil, it is desirable to have means whereby the flow may be positively cut off near to the end of the spout in order to reduce delay caused, by draining the heavy oil from thebody of the spout.

It is therefore one of the objects ofthe present invention to provide an improved spout having a positively operatedllift valve located in said spout and nearV the end thereof'.

' According to one feature of my invention I provide a yspout for drums, cans or other containers for 4oil comprisinga nozzleV adapted to screw on to an attachment member integral with or lined to said container andra lift valve enclosed -in said nozzleand adaptedY to g. close the oil passage through said attachment member7 said valve being moved positively,to open or close said passage,"by rotating said nozzle on said attachmentA inember.`

According to a further feature, the sprout comprises an attachment member by'means of which said spout is attached to Vsaid contaiiier, a nozzle rotatable on said attachment member, a lift valve enclosed in said nozzle and adapted to close the oil passage through 1 said attachment member, said valve being inoved'positively to open or close saidpassage by means of portions on said nozzle engaging said valve. i i i Y A further object of my inventionis to proii vide means for preventing thev removal of attachment A member 'but is prevented from being screwed from said member. Y

According to a still further `feature the attachment member is provided or formed same. Y

With a seat with which said lift valve is adapted to engage Vfor closing the oil passage through said attachment member.

The valve may have a conical or part conical or other suitably shaped portionengaging a correspondingly shaped seat on said attachment memben l According to a'stillfurther feature of myv .invention the nozzle is-provided with one or `of an annular cannelure pressed inthe body of said nozzle after said valve has been inserted therein and adapted to raise said valve from its seat for opening the oil passage.

The head or shoulder on the valve may beof hexagonal or other noncircular forni which can be engaged by said caniielure without closing the `passage, of oil between them. Y f A further projection or portion -inay be provided 'on or in said nozzle adapted to engage the head, on the Vopposite side-to that engaged by said canneiure, forfclosingsaid oil passage when desired. Y Y f' lReferring to the drawings Yeo Figurel showsan outside side elevation of'a preferred form of spout constructed in accordance with this invention.

Figure l2 shows a longitudinal section of Figure 3 shows a plan view taken onthe line 3, 8, of Figure 2.

In the prefered construction illustrated by the accompanying drawings the spout comprises 'an attachment member l having an internally screwv threaded portion 2 by means of which theY attachment member and the spout are iiXed to the drum or other oil container, a washer 3 of cork or other suitable material being inserted in thisscrew threaded portion to forina liquid tightv joint between the attachment member and the drum.

This attachment member is conveniently `of cylindrical form and isprovided with a knurled portion 4 to facilitate the attachment to the VVcontainer or instead of :thisf portion a hexagonal or othernoncircularrportion may be provided so that the spout may be iXed to the container by means of a suitable tool.

The attachment member' is also provided with a screw threaded extension 5 through which passes the oil passage Y6, a nozzle or spout 7 being internally screw threaded and adapted to screw on the threaded portion 5 of the attachment member.

This nozzle may be of any convenient form or length and is provided with one or more knurled portions 8 by means of which the nozzle may be rotated on the threaded portion 5 of the attachment member.

In the end 9 of the threaded shank 5 a valve seat 10 is formed, this being of part conical form and a lift valve 11 is provided in the nozzle, this valve having a conical portion 12 adapted to engage the part conical seat 10.

This portion 12 may be ot any other convenient shape and may be part circular in cross section, the seat 10 on the attachment member being shaped to correspond.

The valve 11 is moved on to or from the seat 10 by means of projections on the nozzle so that when the nozzle is rotated on the threaded shank 5 the valve is raised or lowered from or on to its seat.

One of these projections comprises an annular cannelure 13 pressed in the body of the nozzle after the valve has been inserted therein and this cannelure is adapted to engage a shoulder or head 14 on the body of the valve.

The head or shoulder is of hexagonal shape as shown in Figure 3 so that although the cannelure can engage the corners of the head or shoulder tor raising the valve, the oil passage is not closed as the oil can pass through the spaces left between the cannelure and the Hats on the head.

The head oi shoulder 14- is shown of hexagonal form but may be of any other noncircular orm in cross section so that spaces are left between the flats of the head and the cannelure 13.

For closing the oil passage after the valve has been raised from the seat 10, the nozzle is formed with a portion of reduced internal diameter as shown at 16 so that when the nozzle is rotated in the direct-ion opposite to that in which it is rotated for raising the valve from its seat this portion 16 engages the head or shoulder 14C at the opposite side to that engaged by the cannelure 13 and the valve is moved downwardly into engagement with the seat 10 to close the oil passage from the container. c

The portion 16 leads to the outlet passage 17 and the end of the nozzle may be of reduced diameter as at 18 to conform to the internal shape of the nozzle.

In order to prevent the nozzle being screwed entirely Vtrom the threaded shank 5 an annular-channel 19 is formed in the shank 5 and projections or a cannelure 20 are pressed in the body of the valve to work in this channel 19 so that although the nozzle can be rotated on the threaded shank 5 it cannot be removed entirely therefrom owing to the projection or cannelure engaging the end of the channel 19.

This pressed in portion is conveniently formed between the knurled portions 8 on the nozzle.

nstead of pressing a cannelure round the entire periphery ot the nozzle, one or more projections may be pressed into the body of the nozzle ai'ter it has been screwed into position on the attachment member, these projections then forming the equivalent of the cannelure 9.0.

Similarly projections may be pressed in the body of the nozzle near the upper end thereof to replace the cannelure 13 or the portion 16 of reduced diameter so that the lift valve can be moved in one or both directions by means of these projections when the nozzle is rotated on the threaded shank 5.
